Complete story — includes the ending
When an Air Marshal turns up dead on a flight on which Mac is a passenger, the victim it turns out, isn't a Marshal at all. The real Marshal was killed earlier and his ID stolen. Meanwhile, Stella prepares for a baseball game during which the teams are made up of police against firemen; one with whom she is very friendly. Note: The Who reference: Mac uses the expression "the song is over" to let the perpetrator know that he has found out the truth about the murder.
